Self-expanding focusing electrode and photomultiplier tube for photomultiplier tubes.

摘要

A photomultiplier tube based on an auto-expanding focusing electrode (102) and an auto-expanding focusing electrode, and in the sealing process of the photomultiplier tube, the auto-expanding focusing electrode contacts the trigger mechanism to expand the focusing electrode, The size of the focusing electrode in the radial direction is increased.
